hard drive partition question
 

I have a 200 gb hard disk, by default HP has partitioned into two drives C: and D:, drive C: is 195 GB and D: is 5 GB. I would like to repartition it so as to make my D drive bigger say about 80 GB, How to I do that without corrupting my C drive or my operating system which is windows xp home.

I've always been a fan of partition magic, you can use the trial to re-size your partition :)
